Abstract

The utility model discloses a structural diaphragm coupling belonging to the coupling of the mechanical transmission device and comprising a diaphragm 1, a support ring 3, a fastening ring 4, a half-coupling 5, a bond 6, a shaft 7 and a bolt 8. The utility model is characterized in that transition diaphragms 2 are respectivly arranged between each support ring 3 and the diaphragm 1 as well as between the fastening ring 4 and the diaphragm 1. Transition diaphragms 2 are firmly fixed with the diaphragm 1 through the support ring 3 and the fastening ring 4. The utility model distributes the stress concentrated at the joint of each diaphragms and reduces the possibility of diaphragm damage and prolongs the working life of the coupling.

Description

A kind of structure diaphragm coupling
Technical field:
The utility model relates to a kind of coupling of mechanical transmission, especially the motion between prime mover (as motor, internal-combustion engine etc.) and the working machine (as pump, speed reducer etc.), the coupling arrangement of transmission of power.
Background technique:
Diaphragm coupling is a kind of novel coupler, have and to transmit bigger torque, allow bigger Displacement error, allow high speed rotating, relax impact shock, need not lubricate, be convenient to advantages such as installation and maintenance, be widely used in industries such as military affairs, shipbuilding, aviation, petrochemical industry, machinery, can replace coupling arrangements such as gear coupling, rubbercushioned sleeve bearing coupling.Yet, since coupling in manufacturing, installation, using process, may exist irrational angle, axially or (with) radial displacement, and excessive impact shock may cause in the diaphragm coupling component---the damage of diaphragm unit of the easiest damage.Its damage can directly have influence on the safe in utilization and personal safety of coupled equipment, is difficult to estimate if damage its consequence as the coupling on tank, the warship; Have influence on cost of production, if damage, the loss that stopping accident causes may reach millions of units as the coupling on the petrochemical plant device.
Summary of the invention:
The technical problems to be solved in the utility model is to provide a kind of and can reduce the possibility that diaphragm is damaged, a kind of structure diaphragm coupling in the working life of raising coupling.
The utility model provides a kind of a kind of structure diaphragm coupling with following structure for solving above technical problem.It is by diaphragm 1, bearing ring 3, fastening ring 4, half-coupling 5, key 6, axle 7, bolt 8 is formed, be characterized in, all be respectively equipped with transition diaphragm 2 between each bearing ring 3 and the diaphragm 1 and between fastening ring 4 and the diaphragm 1, transition diaphragm 2 tightly is fixed together with diaphragm 1 by bearing ring 3 and fastening ring 4.
A kind of mode of execution preferably of present technique solution is, it is characterized in that, the tinsel quantity of transition diaphragm 2 determines that according to the coupling size its monolithic quantity is generally the 2-10 sheet, and the monolithic quantity of the transition diaphragm 2 of the big more needs of coupling size is also many more.Disperse to concentrate on the stress of diaphragm connection place, reduce the possibility that diaphragm is damaged, improve the working life of coupling.
Present technique solution another kind mode of execution preferably is, the transition diaphragm be shaped as annular, also can adopt the transition diaphragm of other shapes such as square, triangle as required.
Because the utility model adopts the transition diaphragm, makes the stress distribution of diaphragm connection place be the transition dispersed state, has reduced the stress value at this place, thereby has reduced the possibility that diaphragm is damaged, reach and improve the coupling purpose in working life.
Description of drawings:
Fig. 1---the utility model embodiment's structural representation
Fig. 2---diaphragm group structural representation among Fig. 1
The side view of Fig. 3---Fig. 2
Embodiment:
Provide embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying technical solution.
Embodiment 1, with reference to figure 1-Fig. 3, found out by accompanying drawing, and a kind of structure diaphragm coupling is by diaphragm 1, transition diaphragm 2, and bearing ring 3, fastening ring 4, half-coupling 5, key 6, axle 7, bolt 8 constitutes.Being positioned at the middle diaphragm group of whole device, is to be made of diaphragm 1, transition diaphragm 2, bearing ring 3, fastening ring 4.The diaphragm group is fastened on the half-coupling 5 by 3 bolts 8, and axle 7 is fixed together by key 6 and half-coupling 5.
Diaphragm 1 is made up of 4-20 sheet foil, and the centre is a circular port.Transition diaphragm 2 is by forming with diaphragm 1 material, tinsel that thickness is identical, and its material is 1Cr18Ni9Ti, is shaped as annular, and transition diaphragm 2 is distributed in the both sides of diaphragm 1, is made up of the 4-20 sheet, and it tightens together by bearing ring 3, fastening ring 4 and diaphragm 1.6 groups of bearing rings 3 and fastening ring 4 are evenly distributed.
Working principle: moment of torsion is passed on the half-coupling 5 through key 6 by axle 7.Because half-coupling 5 and diaphragm group adopt the articulation hole Bolt Connection, promptly bolt 8 and half-coupling 5 and diaphragm group adopt to cooperate and connect, so moment of torsion passes on the bolt 8 from half-coupling 5, by bolt 8 moment of torsion are passed on the diaphragm group.And the diaphragm group passes to the bolt of opposite side with moment of torsion, and the half-coupling of this bolt and opposite side links, so moment of torsion is passed to the half-coupling of opposite side, the key by opposite side passes on the axle of opposite side at last, finishes the transmission of power and motion.
In like manner, the technical solution according to the utility model provides can also provide other embodiment.As comparing with above embodiment 1, the structure of other parts is constant, and only changes the embodiment of tinsel quantity on the transition diaphragm; Perhaps compare with above embodiment 1, the structure of other parts is constant, only changes the embodiment of transition film plate shape.
